Changing the gradle version?

I am working with the fabric generator (https://mcreator.net/plugin/112752/another-fabric-generator-1201   with the newest version) and I'm trying to add some dependencies, but for that I needed a newer version of loom, so I tried to do that, but I need a newer version of gradle...

and I don't know how to change the gradle version

minecraft: 1.20.1

fabric: 0.14.21

loom: 1.6-SNAPSHOT

gradle: 8.3 (needs to be 8.6)

sorry if my English is bad
